Abstract
Foliar and root carbon isotope composition (δ 13C) of grassland communities on the Qinghai-Tibet Plateau, China, was obtained by the biomass weighting method and direct measurement. We investigated the characteristics and altitudinal patterns of foliar and root δ 13C and determined which environmental factors influenced foliar δ 13C most. Foliar δ 13C of alpine steppe was significantly higher than that of alpine meadow and temperate steppe. For alpine meadow, root δ 13C was significantly higher than of foliar δ 13C. Foliar δ 13C increased with altitude at an average rate of 0.60‰ km−1 for the whole grassland ecosystem. This rate was lower than that at species level. However, there were no significant relationships between root δ 13C and altitude. Atmospheric pressure was a more important factor than temperature and precipitation in its influence on the altitudinal pattern of foliar δ 13C at the community level.
